Thanks difarn - my iPhone connects to the hub OK, but there's something on the PC which is preventing the adaptor turning on. It shows in network connections, but as disabled (Win XP, by the way). I tried last week with a different make adaptor and had the same problem. I can't really get my head round the setup of two connections!

Just been down to the vets to bring the PC home for a fiddle.

Connects to my wireless router OK and, after plugging in the ethernet cable, wireless still working! The ethernet connection at the vets isn't to the internet as such, but a dedicated vet's network. Don't see how that can affect things. I'll take it back in the morning and try connecting to the hub with the ethernet cable disconnected. If it works, I'll reconnect the ethernet to Vetcomm and see what happens. If not Ill run through your suggestions.

Will report back when I've done that. Thanks for your interest difarn.

Hmm - posted a response earlier, but it hasen't appeared.

Right. Set up at the vets - wireless adaptor enabled, but could see no networks. Brought the PC and the Home Hub back home. Switched both on (HH not connected to the phone line as different ISP) and the adaptor saw the HH straight away. Was able to access the config pages on the router.

Am now at a loss as to why it worked here but not there. Wondering if it could be interference? Might try changing to a fixed channel here (where I can access the router) then try again?

Will do. I'll change it before I go - may not be until Monday, but will report back.

Cutting a long story shortish - having random problems in the surgery again (BSODs, no boot etc). Remembered that one of the BSOD tips is to remove peripherals. Unplugged the USB lead to the printer - ALL OK. Put a new lead in ALL OK! So, somehow, a damaged printer lead caused such a variety of problems. One to store away for another day.
